This species is confined to the soft lignum of conifer and birch stumps. Like M. misella it has an immersed thallus which is invisible from above or is present only as a thin grey-green stain from which numerous black, stalked pycnidia arise. Small, black globose or wart-like discs (with purple-brown, K+ green pigment — seen in a squash) are sometimes present. A single record.
